Non-Uniform Deblurring for Simple Lenses Imaging System

Abstract

As a sub-topic in computational imaging, simple lenses imaging provides an alternative way to achieve a close-to-perfect imaging system design, which simplifies the complex, multiple lens elements optical system to one simple lenses, and delivers the aberration correction process to a dedicated reconstruction algorithm. In this paper, we propose an effective blind restoration algorithm for optical aberrations removal without calibrate procedure. In general, our algorithm consists of two steps: a blind non-uniform PSFs estimation and a non-blind reconstruction. The algorithm can be directly used for simple lenses imaging system, and further utilized for aberrations removal cases in traditional optical imaging equipment. We obtain results that are comparative with the pre-calibrate non-blind restoration.
